Oh sweet baby jesus on fire that was absolutely terrifying... I was trying to get a bite-transmission version of vampirism working and found the dark age mod (which is kinda like a spiritual successor to the fear the night mod) and incorporated the master and elder vamps along with the default randomly generated ones. Did some world generation, got an idea where some were, and started heading out to try and ambush a master/survive long enough to drink their blood and run right?
On the way out I have an asterisk zoom over to me on the travel map, now, I'm geared up nicely but hadn't yet done much wrestling/dodging/shield/armor training as I intended to do it near the city where the master was... so the ambush hits me and it's an elder vampire human recruit, totally nude for some reason... I guess just to add to the "OH GOD WHAT IS HAPPENING" effect?
So they see me and use the vampiric speed boost and go from being a good fifteen squares away to being two squares away by the time I move once, I barely managed to get an arm up and slow them down as I got tackled and thankfully I've got a lot of practice at getting out from between the legs of an enemy... though I did have to savescum the fight (I had saved not long before the ambush as I had just crossed a looooooong haunted mountain range on foot) twice, and even knowing what they were gonna do it still came down to my attempt at ending the fight (got an option of a tricky/square neck shot) and lucking out by breaking their spine, producing a very fast, very bitey, but otherwise harmless snake.
Sheesh... and after going through that, after figuring out how to get close enough to the master (he was the head priest at a citadel, so I approached him from a distance asking about troubles and then hacked off an arm once I got an easy shot available, he is still pretending to be human so he freaks and runs, I grab the blood and save to check something...
*get back in after the save*
*test drink the blood*
*nothing... it doesn't work on dorfs*
...shit.
